The cluster administration overview is for anyone creating or administering a Kubernetes cluster.
|

It assumes some familiarity with core Kubernetes [concepts](/docs/concepts/).

|
||
集群管理概述面向任何创建和管理 Kubernetes 集群的读者人群。
|
||
我们假设你大概了解一些核心的 Kubernetes [概念](/zh/docs/concepts/)。

## Planning a cluster
|
||
|
||
See the guides in [Setup](/docs/setup/) for examples of how to plan, set up, and configure Kubernetes clusters. The solutions listed in this article are called *distros*.
|
||
|
||
Not all distros are actively maintained. Choose distros which have been tested with a recent version of Kubernetes.
|
||
|
||
Before choosing a guide, here are some considerations:
|
||
-->
|
||
## 规划集群 {#planning-a-cluster}
|
||
|
||
查阅[安装](/zh/docs/setup/)中的指导，获取如何规划、建立以及配置 Kubernetes
|
||
集群的示例。本文所列的文章称为*发行版* 。
|
||
|
||
{{< note >}}
|
||
并非所有发行版都是被积极维护的。
|
||
请选择使用最近 Kubernetes 版本测试过的发行版。
|
||
{{< /note >}}
|
||
|
||
在选择一个指南前，有一些因素需要考虑：
|
||
|
||
<!--
|
||
- Do you want to try out Kubernetes on your computer, or do you want to build a high-availability, multi-node cluster? Choose distros best suited for your needs.
|
||
- Will you be using **a hosted Kubernetes cluster**, such as [Google Kubernetes Engine](https://cloud.google.com/kubernetes-engine/), or **hosting your own cluster**?
|
||
- Will your cluster be **on-premises**, or **in the cloud (IaaS)**? Kubernetes does not directly support hybrid clusters. Instead, you can set up multiple clusters.
|
||
- **If you are configuring Kubernetes on-premises**, consider which [networking model](/docs/concepts/cluster-administration/networking/) fits best.
|
||
- Will you be running Kubernetes on **"bare metal" hardware** or on **virtual machines (VMs)**?
|
||
- Do you **want to run a cluster**, or do you expect to do **active development of Kubernetes project code**? If the
|
||
latter, choose an actively-developed distro. Some distros only use binary releases, but
|
||
offer a greater variety of choices.
|
||
- Familiarize yourself with the [components](/docs/concepts/overview/components/) needed to run a cluster.
|
||
-->
|
||
- 你是打算在你的计算机上尝试 Kubernetes，还是要构建一个高可用的多节点集群？
|
||
请选择最适合你需求的发行版。
|
||
- 你正在使用类似 [Google Kubernetes Engine](https://cloud.google.com/kubernetes-engine/)
|
||
这样的**被托管的 Kubernetes 集群**, 还是**管理你自己的集群**？
|
||
- 你的集群是在**本地**还是**云（IaaS）** 上？Kubernetes 不能直接支持混合集群。
|
||
作为代替，你可以建立多个集群。
|
||
- **如果你在本地配置 Kubernetes**，需要考虑哪种
|
||
[网络模型](/zh/docs/concepts/cluster-administration/networking/)最适合。
|
||
- 你的 Kubernetes 在**裸金属硬件**上还是**虚拟机（VMs）** 上运行？
|
||
- 你是想**运行一个集群**，还是打算**参与开发 Kubernetes 项目代码**？
|
||
如果是后者，请选择一个处于开发状态的发行版。
|
||
某些发行版只提供二进制发布版，但提供更多的选择。
|
||
- 让你自己熟悉运行一个集群所需的[组件](/zh/docs/concepts/overview/components/)。
